Look for stems missing some leaves and wilted leaves hanging down. You may find white cocoons and their hornworm hosts nearby.
Secondly, where do tomato hornworms hide during the day? They tend to hide beneath leaves and along interior stems during the day, becoming active, and munching their way through your tomato patch during the cooler evening hours. These caterpillars start out as small, inconspicuous green worms that look like they could never lay waste to a whole tomato plant.
